VALENTIN BACH, 0F MANHATTAN BE SLAB SCOOP FOR ICE CREAM.

p for ice cream the form of thin An object of my invention is a scoopfor dispensing ice cream, is eut or scooped from having ice cream inbulk, in

in which the ice cream a can or the like the form of a slab. ln theprior practice for forming slabs of ice cream.l suoli asare used inoonnection with making ice cre between wafers of pastry or been thecustom to out of ice cream or the like. the person dispensing such i amsandwiches the like, it has the slabs from bricks This' necessitates cecream sandwiclies to have aV stock of ice cream bricks which are moreexpensive readily handled than ice cream in and are less bulk in a canwhich may be maintained continuously in a freezing temperature, onlyopened when it is necess the ice cream.

such cans being dispense ary to Therefore, with the implement of myinvention l may insert this through the open top of an ice cream can andamount of sever a certain the ice cream in the form of a slab,

which may be placed between 'a pastry and form an ice cream sold in theform of a slab on or the like.

Another object of my invention is the sandwich, or may be dish a servingstruction of a scoop which may be used to dispense different kinds ofice cream in thin layers, or formed into one stance,

vwith my scoop I may slab. For intake a thin layer ofv vanilla ice creamfrom one can, a

if desired,

say of strawberry from another layer,

from another can, these integral slab having invention is the conwhichmay be readily hand to sever the ice and remove same from the can and bymanipulation of a finger, the slab may be expelled on a wafer or aserving dish.

ln constructing my invention I have a suitable frame-work tacleextending tacle having` sharp edges,

with an open ended recepbelow the base, this recepand if desired,

it may be formed rectangular or any other shape.

A knife is manipulated by the fingers to cut through the ice -creambelow the lower cutting` edges of the thus sever the icecream inreceptacle and Vthe receptacle 1927. Serial No. 193,508.

downwardly on a plunga false base out- My invention may be more readilyunderstood from the following drawings, in which: Figure 1 is a sideelevation of my scoop,

cutting the slab The main stationary parts of my scoop comprise asuitable frame 11 which has arcuate sidewalls 12, arcuate base 18 and arigid cap 14 secured to the upper ends of the sides.

Extending laterally from the cap there is a fixed bar 15 on which ahandle 16 is secured. Depending fro are ribs 17 and below vsu m the basethere chv ribs there is formed a slab-receiving receptacle 18, thishaving arcuate side walls 19 and end walls 20. These walls are formedcomparatively thin andA may, if desired,

have the lower edge sharpened, as indicated at 21. A bridge 22 issuspended by means of straps 23 from the cap 14. A false base 24 isformed of preferably a thin plate bent on a curve,

and to this is secured a backing lug 25.

To this lug there is secured a stem 26 which passes upwardly through anopening 27 in the base 13 and extends through a guide opening 28 in thebridge 22. A pin or collar 29 is secured compression spring 30 the uppersurface of the ba normally tending to raise the position shown in Fig.

to this stem and there is a between such pin and se 13, this spring thevfalse base into When it is desired to scoop a slab from bulk ice creamin a can,

into the bulk icc cream so the scoop is pressed that the sidesl 19 and20 of the receptacle 18 are forced into such bulk material, that is,

until the downward movement of the scoop is preventedby the false baseThe cutting mechanism 24. for severing the slab from the bulk issubstantially as iollows:

A knife 3l is mounted on a pair oi' arms 32 which arms are shown attheir-lower part 33 as extending around the sides i9 oiE the receptacle,and have an upper extension 34 preferably passing on the outside oiE theside walls 12. rlhe upperI ends are secured to a rock shait 35 by setscrews 36 or the like so that on rocking this shaft, the knife is swungfrom the position shown in Figs. l,

` 3 and 5 to the opposite side of the receptacle.

lll)

As the kniie describes an arc having the shaft. 35 as a. center, thelower edge 37 of the sides 19 of the receptacle are curved, using theshalt as a center. rllhe curvature of the false base 24 is alsoconcentric to the lower edge ofthe receptacle so that the slab will beof equal thickness in all parts. i

A pair of upper segmentary gears 38 are keyed or otherwise secured on'the shaift and a pair o1" lower segmcntary gears 23) are mounted on ashaft 40 which extends. between the side walls l2, and formed integrallywith one ot these latter gears there an operating arm 4l having` alinger grip 42. A coiled spring 43 is wound on the iiXed shaft 40 andinterengafrcs between the base 13 and either one or. both of thesegnientary gears 39, this spring being` tensioned to normally hold saidgears in the position shown in Figs. l, 8 and 5. When the receptacle isproperly embedded in the bulk ice cream with the operator holding thedevice by the handle in the hand, the linger grip 42 is preferablyengaged by the iirst finger and pulled upwardly, thus rocking the lowergear 39 and transmitting the motion to the upper scgmentary gear 38which rocks the rock-shaft and hence swings the knife through theinstrumentality of the arms 32 from the position shown in Figs. l, 3 and5 to the opposite side of the receptacle. This severs part oi the icecream from the bulk. Y

The means for eiqaelling` the slab coinprise a cani 44 which is looselymounted on the rock shaft 35 and has a thumb enga^'ing end 45. This camin the position Jor i'illing the receptacle is in the position shown inFig. 5. To expel the ice creanrit is merely necessary to thrust with thethumb on the end 45, thus shifting the cam from the position shown inFig. 5 to that in Fig. 3, this action depressing the stein 26 and movingthe false base 24 from the position shown in Fig. 5 to that of Fig. 3whereby the slab may be deposited on a waiter or a serving dish.

The manner of securing a slab having` dii"- erent distinct layers isaccomplished by having a series ot notches 4e on the cam, thus the notchnearest the lower end the cam 47 may engage the upper part oi the stem26 which raises the false base slightly or to the false base above thelower edge 3T of the receptacle and the receptacle may be filled to thisextent with one type ot ice cream and the knife manipulated to severthis thin layer. The thumb grip 45 may then be moved upwardly untilanother notch engages the upper part of the stein 26 and another l'lavoror color may be severed from anotl n' can, this being cut by the knifeas above ydcscribed. t is obvious at l may provide many of these notchesas l desire so that more than two distinct layers of ice cream may becut trom the bulk troni different cans, before the false base is in itsAcomplete upper position, as shown in 5 with the upper part 47 of the camengaging the upper part of the stein. 'When such composite slab isexpelled from the receptacle in the 'manner above described, it providesa slab having these distinct layers givinc diilqerent'iiavors and apleasing appearance.

ln manipulating my scoop it is desirable that it be maintained rathercold, and to this end it is desirable to stand it in a body ot coldwater so that the receptacle iscovcred by the water, or else to placethe whole instrument inside of a freezer. However, 'the slight meltingot the ice cream in using the implement is advantageous as it Apreventssticking of the ice cream to the receptacle 24. it also allows readycutting by the knife 3l. lt is obvious that the shape and design of myscoop may be materially changed and provide Vfor cutting round slabsorvthose ot' any other fancy shape which may be desired. it is also ob-7ious that the scoop may be utilised for severing other types ot productother than ice cream, but the latter the immediate use to which l amplacing my invention.
